A transparent organic light emitting display device and a method of manufacturing the transparent organic light emitting display device are provided. The transparent organic light emitting display device comprises a plurality of sub pixel regions, each having a emissive area and a transmissive area, a thin film transistor disposed in the emissive area, and an organic light emitting element electrically connected to the thin film transistor. While the emissive area emits light to display image on the display device, the transmissive area allows the external light to be passed through the display device so that objects behind the display device can be viewed simultaneously with the displayed image.
